It could be 1,870. You multiply 70 by 25 which gives you 1,750, than you multiply 5 by 24 which gives you 120 and your answer will total out to 1,870

Bob is driving along a straight and level road toward a mountain. At some point on his trip, he measures the angle of elevation

DerKrebs [107]

Answer:

Option A.

Step-by-step explanation:

Distance between Bob and the center of the mountain at the base = 19,427.5 ft.

Angle of elevation to the top of the mountain = 25°11'

We know that

1 degree = 60 minutes

1/60 degree = 1 minute

$25^{\circ}11'=25^{\circ}+\frac{11}{60}{\circ}\Rightarrow 25^{\circ}+0.183^{\circ}=25.183^{\circ}$

Let the height of the mountain be h.

In a right angled triangle

$\tan\theta = \frac{opposite}{adjacent}$

$\tan(25.183^{\circ}) = \frac{h}{19427.5}$

$\tan(25.183^{\circ})\times 19427.5 = h$

$h=0.4702\times 19427.5$

$h=9134.8105$

$h\approx 9135$

Therefore, the height of the mountain to the nearest foot 9135. Option A is correct.

Ben and his two friends are going on a 1,500-mile road trip. The car uses 3 and one-fourth gallons of gas every 100 miles. Gas c

Phoenix [80]

Answer:

Each will pay $61.75.

Step-by-step explanation:

How many gallons were used?

Each 100 miles, 3 + 1/4 = 3 + 0.25 = 3.25 gallons are used. The trip has 1500 miles.

100 miles - 3.25 gallons

1500 miles - x gallons

$100x = 1500*3.25$

$x = \frac{1500*3.25}{100}$

$x = 48.75$

Cost

Each gallons costs $3.80.

48.75 gallons cost 48.75*3.80 = $185.25

Split among the three friends envenly, how much will each pay?

185.25/3 = 61.75

Each will pay $61.75.

Un medico receta a un paciente tomar una pastilla cada 6 horas y un jarabe cada 8 horas. Si

Xelga [282]

Queremos ver cuando será la proxima vez que una persona <u>tome dos medicamentos al mismo tiempo</u> dado que los toma en intervalos regulares.

Veremos que luego de 24 horas el paciente volvera a tomar ambos medicamentos juntos.

Sabemos que el paciente toma una pastilla cada 6 horas y un jarabe cada 8 horas.

El paciente volvera a tomar ambos medicamentos juntos en el primer multiplo comun de 6 y 8.

Para encontrarlo podemos simplemente escribir los multiplos de cada uno y ver cual es el primero que aparece para ambos números:

6*1 = 6

6*2 = 12

6*3 = 18

6*4 = 24

y

8*1 = 8

8*2 = 16

8*3 = 24

Podemos ver que 24 es un multiplo comun (el primero) de 6 y 8.

Esto significa que luego de 24 horas el paciente volvera a tomar ambos medicamentos juntos.
